Removable tripod foot with securement

Abstract

Installation of a removable tripod foot is facilitated by a cross-axis aperture in the foot and loosening of the threaded connection of the foot and the tripod's leg is resisted by a resilient element engaging interfacing surfaces of the foot and the leg.

We claim: 
     
         1 . A foot for a tripod comprising:
 (a) a body including an interface region including a portion arranged to engage a terminal portion of a leg of a tripod and an elongate threaded portion with a terminal portion at the end thereof furthest distant from said interface region arranged substantially normal to the portion of the interface region, where said interface region has an outer diameter, where said elongate threaded portion has an outer diameter, where said outer diameter of said interface portion is greater than said outer diameter of said threaded portion;   (b) said interface surface defining a depression in a circular pattern encircling said elongate threaded portion, where said circular pattern is suitable for receiving a resilient element for engaging the interface surface that includes a portion extending proud of the portion of said interface surface arranged to engage the leg of a tripod;   (c) wherein said interface region includes an outer peripheral edge and said depression in said circular pattern is sized such that at least a portion is within a region defined by said outer peripheral edge of said interface region;   (d) wherein said depression in said circular pattern has an outer diameter and further said body includes a body outer peripheral surface with an outer diameter proximate said outer peripheral edge;   (e) wherein said body includes a crenated wall defining a plurality of facets arranged to engage a surface supporting said tripod, wherein each of said facets has an end portion thereof to engage said surface supporting said tripod;   (f) where said outer diameter of said depression in said circular pattern is greater than said outer diameter of said elongate threaded portion;   (g) wherein said body defines an opening in said body, wherein said body defines said opening in said body at a location aligned with said elongate threaded portion.   
     
     
         2 . The foot for said tripod of  claim 1  further comprising the resilient element that comprises an elastomeric toroid retained in the depression with a portion of a surface of the resilient element projecting proud of the portion of the interface region arranged to engage the leg of a tripod. 
     
     
         3 . The foot for said tripod of  claim 1  wherein said elongate threaded portion of said body comprises a portion defining a threaded aperture. 
     
     
         4 . The foot for said tripod of  claim 1  further comprising said tripod. 
     
     
         5 . A foot for a tripod comprising:
 (a) a body including an interface region including a portion arranged to engage a terminal portion of a leg of a tripod and an elongate threaded portion with a terminal portion at the end thereof furthest distant from said interface region arranged substantially normal to the portion of the interface region, where said interface region has an outer diameter, where said elongate threaded portion has an outer diameter, where said outer diameter of said interface portion is greater than said outer diameter of said threaded portion;   (b) said interface surface defining a depression in a circular pattern encircling said elongate threaded portion, where said circular pattern is suitable for receiving a resilient element for engaging the interface surface that includes a portion extending proud of the portion of said interface surface arranged to engage the leg of a tripod;   (c) wherein said interface region includes an outer peripheral edge and said depression in said circular pattern is sized such that at least a portion is within a region defined by said outer peripheral edge of said interface region;   (d) wherein said depression in said circular pattern has an outer diameter and further said body includes a body outer peripheral surface with an outer diameter proximate said outer peripheral edge;   (e) wherein said body includes a spike arranged to engage a surface supporting said tripod;   (f) where said outer diameter of said depression in said circular pattern is greater than said outer diameter of said elongate threaded portion;   (g) wherein said body defines an opening in said body, wherein said body defines said opening in said body at a location aligned with said elongate threaded portion.   
     
     
         6 . The foot for said tripod of  claim 5  further comprising the resilient element that comprises an elastomeric toroid retained in the depression with a portion of a surface of the resilient element projecting proud of the portion of the interface region arranged to engage the leg of a tripod. 
     
     
         7 . The foot for said tripod of  claim 5  wherein said elongate threaded portion of said body comprises a portion defining a threaded aperture. 
     
     
         8 . The foot for said tripod of  claim 5  further comprising said tripod.
